      Server Description

      A high-density, memory-optimized arm64 platform featuring 192 dedicated physical cores and 1.5 TB of RAM for demanding database workloads.

      Memory OptimizedCompute Optimized

      Amazon Web Services r8gb.48xlarge is a memory-optimized instance featuring 192 dedicated physical cores on the arm64 ARMv9 Neoverse-V2 architecture. Operating at 2.7 GHz on the AWS Nitro hypervisor, it delivers 1536.0 GB of RAM, yielding 8.0 GB of memory per core, alongside a 200 Gbps baseline network bandwidth. The instance does not include local storage or GPU accelerators. Benchmark results show top-tier multi-core CPU performance and memory bandwidth, though single-core metrics and image processing speeds remain average to weak. The server is highly efficient for high-density, memory-intensive workloads. It is optimized for large-scale in-memory databases, Redis deployments, high-throughput static web serving, software compilation, and multi-threaded data processing tasks.

      Workload Profiles

      9.65Score
      Precomputed compound score for Cache Intensive workloads. A weighted average (geometric mean) of benchmark scores compared to their medians: score = ∏ (x_i / m_i)^(w_i / Σw). The score of 1.0 represents a synthetic baseline server with the median performance of each component benchmark; 0.5 means roughly half the performance; and 2.0 means twice the performance of that reference profile. Component weights: 50% Redis RPS (pipeline=1, SET), 20% Redis RPS (pipeline=16, SET), 10% PassMark Memory Mark (composite), 10% Memory bandwidth (read, 16 MB ~ L3), 10% PassMark single-thread CPU. Rationale for component selection: In-memory key-value store workload, mixing direct Redis performance metrics with memory speed and latency benchmarks, and single-core CPU performance profiles.
